Free your body and mind

Put on this track jacket and be amazed by how light it feels. Despite zero spandex content, the fabric has a two-way stretch to give you maximum freedom of movement. Whle the material is breathable and light, it traps a layer of air that provide warmth on cooler days. Like the name suggests, the soft comfort of the CALM JACKET will help put you in the right state of mind before starting your workout.


Pefect for daily wear or light running

The light weight, stretch, and relaxed fit of this jacket will make you want to wear it all the time. When you're ready to go running, you can also tighten the hem drawstring and slip your hand through the thumbholes sleeves. For a relaxing run, we recommend slipping on the CALM JACKET and aiming for a heart rate of 180 minus your age (±5). A slower pace will improve your blood circulation while also calming your body and mind. That's why we named this the CALM JACKET.



Choose Sustainable Fabrics

  • wool-T in the room
  • non-mulesing merino wool
  • Giving old clothing a second life

    It is estimated that around 100 billion pieces of clothing are produced every year, but only 20% of that is actually worn. The remaining 80% ends up in landfills. Unlike other recycled polyester (generally derived from PET plastic bottles), RENU®️ takes a circular economy approach and creates new material from recycled clothing and fabric scraps. The polyester produced by RENU®️ partner factories has the same quality as petroleum-derived polyester, and is more sustainable.

  • No more spandex

    It wouldn't be an exaggeration to say spandex, or polyurethane, has revolutionized sportswear with its outstanding stretch and lightweight properties. It can be found blended into most functional wear today. However, spandex production uses a lot of chemicals, making it an unsustainable fabric. It also deteriorates quickly, wiht a lifespan of only two to three years. The CALM JACKET doesn't use any spandex but still provides sufficient stretch.
